European Defence Photonics: Critical Supply Chain Bottlenecks in Optics & Infrared Sensors

The report addresses the growing strategic problem posed by the physical availability of military sensing and targeting components in Europe. It frames information superiority not as a purely digital or software challenge, but as a material and industrial one, rooted in the production of electro-optical, infrared and photonic hardware. Drawing on post-2022 NATO and EU priorities, the text shows how defence readiness, precision strike, integrated air and missile defence, and training realism depend on a constrained supply chain of sensors, seekers and related subsystems. It explains why sensor shortages have emerged as a limiting factor in the scaling of missiles, drones and armoured platforms, and why these constraints persist despite funding and political commitment, due to low production volumes, complex qualification processes and export-control regimes. The report then guides the reader through a detailed, structured analysis of the European sensory supply chain. It explains the operational role of EO/IR systems across missiles, UAVs, ground vehicles and air-defence architectures, clarifying spectral bands, cooled versus uncooled technologies, and the function of active photonics such as lasers and DIRCM. It examines upstream constraints in materials and optics fabrication, infrared detectors and focal plane arrays, cryogenic cooling, and active photonic components, before mapping the European industrial ecosystem by role and capability.
